My opinion:
Didn't really like them, sound wise they were pretty good, but you cant rotate the cups at all, the top band is pretty hard, so it's not really suitable for extended periods of time. Oh and the detachable cable is obviously a good idea, but not well manufactured, it doesn't sit well in the port, which means it very easily pops out slightly, making the headphones either lose audio, or half of the signal. Oh and the microphone sucked. Obviously this could all be from a defective pair, but I give it a 3/10
Something more conventional would be something from Shure, or the Audio Technica ATH-M50's.
